Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532022, here are decompositions:

19 + 31532003 = 31532022
101 + 31531921 = 31532022
113 + 31531909 = 31532022
139 + 31531883 = 31532022
271 + 31531751 = 31532022
373 + 31531649 = 31532022
383 + 31531639 = 31532022
443 + 31531579 = 31532022

Showing the first eight; more decompositions exist.
